Scan the codebase and (re)build the structural graph using tree-sitter AST parsing. Auto-detects 20 languages and frameworks. Runs cross-stack resolvers (HTTP, gRPC, GraphQL, WebSocket, queues, events, CLI). Call on first use or after major refactors.

Repo overview: node/edge counts, detected kinds, entry points, and a dense text preview. Call this first to orient before using other tools.

Full structural graph in dense sigil notation — the complete map of entities, relationships, and scopes. This is the primary context tool: feed it to the LLM so it can navigate without reading files.

End-to-end flow for a feature: entry point through service layer to data store, rendered as layered tiers. Call after status to drill into a specific feature.

Shortest path between two nodes, showing each hop with tier transitions.

Blast radius analysis: fan out from a node to see everything it affects (downstream) or depends on (upstream), grouped by tier.

All direct connections to and from a node, one hop in each direction.

Spreading activation from seed nodes — finds the most relevant nodes in the graph relative to your seeds. Uses Personalized PageRank with domain-tuned edge weights. Returns ranked results by relevance score.

Find nodes by name or qualified name pattern. Returns matching nodes with their kinds and qnames.

Visual ASCII graph. With node: tree of children and connections. Without: full overview with counts.

Re-generate the graph from source. Call after code changes.
